Well, I shall try to answer this question. Before you thinking of buying animal, you have to know where you want to place it.
My dog-placed outside in a garden-at nights placed in my bed. lol
My cats-running arround a house-they can really go anywhere.
Lizards- I have a room just for them. Made terariums at home for them, so well kept away from predators.
Chameleons-they have another room for their terariums.
Ferrets? they have a big wooden cage, if they are not in, they probably running arround me and driving me mad.
So all in once-if you wish to have a ZOO, you need to have space. I live in a big house so I do really have space.
All animals kept in a good condition. I am a grown girl so I do care for all my pets with love.
